I'm beginner in Oracle, but I'd like know if it's a good practice always restore the control-file of a backup-set before restore the database. I ask this because always when I restore the control-file I need open the database with reset-logs option and I don't know if it's a good practice to do this.

If the answer is no, so when I need restore the control-file?

    do you use an RMAN catalog for your backups? – miracle173 Oct 28 '19 at 5:52
  • Sometimes, lately I'm using just controlfile in my tests, in my work none database use catalog as well. – Solaire of Astora Oct 28 '19 at 11:22

It depends entirely on the nature of the failure and the need of recovery. The ends-and-outs are too complex to put in a single answer here, but the Database Backup and Recovery User Guide has a whole section of scenarios on "Diagnosing and Responding to Failures". You would do well to study it. And build yourself a private VM under VirtualBox, to practice on.

Recovering a database is the Prime Directive of any DBA.
